<P>PROBLEM TO BE SOLVED: To provide an infusion pump of a peristaltic motion type which is operated by a power-saving drive motor having an excellent slidability and a low torque on a sliding surface such as a finger plate, a disk cam, a guide or the like and which has a small size, a light weight and a low cost in the infusion pump. <P>SOLUTION: The infusion pump of the peristaltic motion type is provided with: a disk cam fixed to a rotary shaft supported by a bearing; a finger plate brought into contact with the outer peripheral surface of the disk cam to move to advance or retract in association with an eccentric rotation of the disk cam; and a guide 4 holding the finger plate from both side faces so as to slidably guide the plate 3. The disk cam, the finger plate and the guide are made of resin molded bodies, which are molded products of a resin composition which does not adhere by mutual contacts. Either of the finger plate and the guide part is a molded product of polyphenylene ether resin. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
